The STAC6 represents the latest developments in stepper drive
technology, incorporating advanced features that will derive the highest
performance from today’s stepper motors. Its Anti-Resonance and
Waveform Damping control algorithms make it a clear market leader.
Some of the advanced features include:
Self Test and Auto Setup: Measures and configures
motor parameters automatically
Anti-resonance: Eliminates midrange instability
Demand Signal Smoothing: Reduces extraneous
system resonances
Torque Ripple Smoothing: Adjusts current waveform
to reduce low speed torque ripple
